From new: Remove handle and bolt to sides with provided screws.
Unscrew wing nut and remove flare from center of unit. Secure same wing nut on center stud.
Place flare on feeder end and fasten with screws and wing nuts provided.
Your unit is now fully assembled.
For unit to operate properly, the feeder end must be 2 ½ -3 inches higher than the back end.
Place unit in shallow water no more than height of sides.
Place shovel full of material in feeder on top of mat. Material should immediately start flowing down sluice box. 50% of material is being trapped behind riffles while the other 50% washes down stream. (This is the proper flow & angle when this is achieved). Note: Water flow is too slow if unit fills with sand and gravel – you then must increase your water flow, angle, or both to achieve the 50% being trapped and the 50% going down stream.

Make sure carpet is dry before storing unit.
